0xA0FE0000:
<begin>
EELITE's Blocks

EIT: (Upwards), descriptors of 16 bytes (4 / 4 / 4 / 4)

Status / Block number / length / offset from the beginning EELITE

Status: 0OFFFFFF - removed S0FFFFFF - working
length: size = length - 1
Displacement: Destination address = 0xA0FE0000 + offset + 1

<end>

--------------------------------------------------------------------------------
0xA0220000:
<begin>
EEFULL's Blocks

EIT: (bottom to top), descriptors of 16 bytes (4 / 4 / 4 / 4)

Status / block number / length / offset from the beginning EEFULL (1)

Status: 0OFFFFFF - removed S0FFFFFF - working
block number: the real number of the block = block number + 5000
length: size = length - 1
Displacement: Destination address = 0xA0220000 + offset + 1
